In the first securing position, the locking member is secured by means of the holding device 34, regardless of the actuating device 20 against movement or adjustment from the release position into the blocking position.

- the blocking element 48 is attached to the housing 12 and in the present case designed as an actuator in the form of an electromagnet.
- the electromagnet is assigned a coupling rod 50. 1, the coupling rod 50 is passed through a corresponding passage opening 56 of the electromagnet and has a stop 52, via which it can be supported on an end face 54 of the electromagnet facing away from the lever arrangement 36.
- the coupling rod 50 acts as a magnet armature can thereby interact with the electromagnet (locking element 48) by the electromagnet magnetically attracts and holds the coupling rod 50.
- a stop 52 facing away from the end of the coupling rod 50 is coupled to the second toggle lever element 40.
- the coupling rod 50 engages in a recess formed as a slot 58 of the second toggle element 40.
- the slot 58 is used to compensate for an angular offset. In other words, the coupling rod 50 can move in the slot 58.
- a relatively small angle ⁇ is established, which is preferably less than 10 degrees.
- the first securing position relates to an adjustment of the lever arrangement 36 from the second to the first securing position by a pre-dead-center position of the lever arrangement 36.
- the lever member 18 and the locking member against undesired movement from the release position are secured in the locked position.
- the actuating spring element would exert a torque about the fourth pivot axis 46 in the counterclockwise direction on the second toggle lever element 40, resulting in a force moving away from the end face 54, however such movement is prevented by tightening the stop 52 by means of the electromagnet.
- the second toggle element 40 is also under load from the example se designed as a torsion spring actuating spring element can not rotate counterclockwise.
- the locking element 48 which acts as a blocking actuator, alternatively acts on the first toggle lever element 38 and blocks the lever arrangement 36 and, moreover, the locking member via the first toggle lever element 38.
- the blocking element 48 may alternatively be designed as a fluid cylinder, a magnetorheologically blockable cylinder or rotor, an electromagnetically or piezoelectrically switchable brake, an electromotively driven spindle and / or as another actuator. Furthermore, it is possible that the blocking element 48 acts directly on the fourth pivot axis 46 of the second toggle lever element 40.
- the stop 52 serves in the present case in particular for adjusting the angle a.
- the arrangement of the stopper 52 is variable.
- Such a stop may be provided, for example, between the toggle lever elements 38, 40.
- an optional actuator in the form of a spring member 60 is provided.
- the spring element 60 is presently on the one hand at least indirectly on the housing 12 and on the other hand at least indirectly, in particular directly, connected to the second toggle lever element 40.
- the spring element 60 in the first securing position, the spring element 60 - as indicated in Fig. 1 by a directional arrow 62 - biased so that the lever assembly 36 is acted upon by means of the spring element 60 with a spring force by means of which the lever assembly 36 is supportively movable from the first securing position ,
- a magnetic force by means of a direction arrow 49 is illustrated, which opposes the electromagnet (locking element 48) of the stop 52 on the coupling rod 50 away from the end face 54 force.
- the holding device 34 has a particularly simple and therefore inexpensive construction. Due to the only relatively small angle ⁇ between the toggle lever elements 38, 40 is at least almost a total, by the Betuschistsfe- derelement supported torque via the bearing of the second toggle element 40 to the housing 12.
- the electromagnet (blocking element 48) only requires a relatively small force in order to maintain the desired angular position of the toggle elements 38, 40 under load, ie in the event of failure of the pressurization of the piston 26.
- the locking member is so easily movable from the release position into the blocking position that the locking element 48 is deactivated and the stopper 52 and thus the coupling rod 50 releases. Then, the locking member is adjusted by means of the biased actuating spring element in the blocking position. Furthermore, no opening spring for a currentless opening of the parking brake 10 is required. Another advantage is that the parking lock 10 opens at least substantially instantaneously, as soon as the locking element 48 is turned off, as is the case for example when switching off the electromagnet.
- Fig. 2 shows the holding device 34 in its second securing position.
- the locking member In the second securing position, the locking member is secured independently of the actuator 20 in the locked position. If, for example, there is a malfunction of the hydraulic device of the passenger car, as a result of which the piston 26 is subjected to pressure, then the locking member can not move into the release position due to the securing by the holding device 34.
- the second securing position relates to an adjustment of the lever arrangement 36 from the first to the second securing position by an over-center position of the lever arrangement.
- the locking member could not move without action of the spring element 60 into its release position, if the locking element 48 would be disabled and thus the coupling rod 50 and thus the lever assembly 36 would not be held on the stop 52.
- An at least almost total, resulting from the unintentional pressurization of the piston 26 force can be supported on the housing 12 via the mounting of the second toggle lever element 40 and via the stop 52.
- the actuating element (spring element 60) can alternatively also act on the first toggle lever element 38 or on the coupling rod 50 of the locking element 48.
- Another variant of the stop 52 is, for example, the direct support of the lever element 18 and the second toggle lever element 40.
- the protection by the over-center position causes in particular the advantage that arbitrarily high torques and / or forces can be supported without loading of the locking element 48. Furthermore, the locking element 48 must be able to apply no excessive forces regardless of any force exerted by the actuator 20 force. Furthermore, the actuating element (spring element 60) does not have to apply excessive forces.
- the blocking element 48 can also be designed as the actuating element.
- the movement of the lever arrangement 36 from the over-dead-center position can also be effected, for example, by the blocking element 48, in particular the electromagnet.
- the coupling rod 50 is moved counter to the directional arrow 49, so that the stop 52 lifts from the end face 54.
- the blocking element 48 can act here as an actuator.
- the solenoid may be configured to drive the coupling rod 50 in two opposite directions. As can be seen from FIG. 2, the angle ⁇ is also set in the second securing position between the directions of force of the toggle lever elements 38, 40.
- the principle described with reference to FIGS. 1 and 2 of the parking brake 10 can also be readily transferred to a locking member of the parking brake 10, which is translationally, ie linearly adjustable between the release position and the blocking position.
- a locking member of the parking brake 10 which is translationally, ie linearly adjustable between the release position and the blocking position.
- the lever member 18, and the first toggle element 38 is instead hingedly connected to a linearly movable and connected to the locking member actuator.
- at least one of the bearings and / or connection points of the parking brake 10 and in particular the holding device 34 is designed as a slot or with a large radial play, so that in addition to the corresponding rotational movement and at least one linear movement as a relative movement between the respective items possible is. If, for example, the bearing point between the lever element 18 and the first toggle lever element 38 is designed as a slot, then overshoots of the gearshift shaft 16 beyond the secured positions are possible without influencing the holding device 34.
- the locking element 48 in conjunction with the spring element 60 in particular for moving the lever assembly 36 and for effecting a movement of the lever assembly 36 from the second securing position.
- FIG. 3 shows an alternative embodiment of the parking brake 10.
- the locking element 48 designed as an electromagnet can interact directly with the second toggle lever element 40 as a holding magnet. By activating the electromagnet this pulls the second toggle element 40 directly, thus keeping the lever assembly 36 in its corresponding securing position.
- the toggle elements 38, 40 are in their Vortotddlinglage, whereby it comes when deactivating the electromagnet and Federkraftbeetzwegung by the actuating spring element to a currentless opening of the holding device 34, so that the locking member can move from its release position to its blocking position ,
- Figs. 4 and 5 illustrate the parking brake 10 of FIG. 1 and 2, transmitted to a translational, ie linear actuation of the locking member.
- the locking member is in this case connected to an actuating element 64 which is translationally movable relative to the housing 12.
- the actuating element 64 is at the same time the piston rod 28.
- the second toggle element 40 is pivotally connected to the cylinder 22 about the fourth pivot axis 46 relative to the cylinder 22 and mounted on the housing 12 via the cylinder 22.
- the locking member is in its release position, wherein the holding device 34 is in its first securing position. Accordingly, the locking member of FIG. 5 is in its locking position, wherein the holding device 34 is in its second securing position.
- the blocking element 48 is deactivated, so that the stop 52 can move away from the end face 54.
